For audio handling on Linux, PipeWire is the currently recommended framework.

PipeWire is a newserver low-leveland user space API that provides a platform to handle multimedia framework.pipelines. It aimsis toa offermodern, capture and playback for bothlow-latency audio and video server designed to work with minimalthe latencylatest audio use cases and supporthandle forprofessional PulseAudio,audio JACK, ALSAinterfaces and GStreamer-based applications.

ThePipeWire daemonwas basedcreated onas a replacement for both the frameworkPulseAudio cansound beserver configuredand the Jack Audio Connection Kit (JACK) server. It provides a unified interface for handling video and audio streams and is intended to be bothflexible anand extensible, allowing it to address not only audio serverbut (withother PulseAudiomultimedia tasks as well, such as video conferencing, screen capture, and JACKother features)multimedia applications. It can also work with different hardware devices, including webcams, microphones, and aprofessional videoaudio capture server.devices.

Additionally,There WirePlumberare istwo session managers to choose from:

• PipeWire Media Session: A very simple session manager that caters to some basic desktop use cases. It was mostly implemented for testing and as an example for building new session managers.
• WirePlumber: A more powerful manager and the current recommendation for a session manager.recommendation. It is based on a modular design, with Lua plugins that implement the actual management functionality.

WirePlumber is the recommended choice, as it is better maintained, receives regular updates and is more feature-rich.
